EMG & NCS

What is Electromyography (EMG) and Nerve Conduction Studies (NCS)?

Electromyography and Nerve Conduction Studies, or EMG/NCS, is the recording of the electrical activity in the muscles and nerves. The study used small devices called electrodes to measure electrical signals transmitted by neurons. The electrodes are taped to the skin in order to gather recordings of the speed and strength of the signals as the muscles contract and relax.
